Problems solved by technology

However, since the target tracking algorithm based on the principle of computer vision requires a large amount of computation, for real-time application systems, the real-time tracking is a key issue. In addition, multi-target tracking is a measure of the tracking sensor performance in human-computer interaction systems. An important indicator of , the re

Abstract

The present invention relates to one kind of six-freedom visual tracking method and system based on microcomputerized parallel processing structure. The tracking process includes the following operation steps: 1) installing artificial marker onto the tracked target, 2) performing view field acquisition of the scene with the artificial marker with several video cameras to obtain the original image, 3) processing the obtained image in computer, and 4) completing the 3D reconstruction of the spatial position and direction of the artificial marker and outputting the reconstructed result via network communication equipment to various man-computer interaction system. The tracking system includes N microcomputers, N image acquiring systems, N network communication cards and one network exchanger. The method and system of the present invention can realize the precise location and tracking of spatial target and has less influence of electromagnetic interference and other advantages.

Description

technical field [0001] The invention relates to a visual tracking method and system in augmented reality and virtual reality (or other human-computer interaction systems), in particular to a six-degree-of-freedom visual tracking method and system based on a microcomputer parallel processing structure. Background technique [0002] Tracking the spatial position and orientation (six degrees of freedom) of helmets or other objects is a key technology in augmented reality (AugmentedReality) and virtual reality (Virtual Reality) systems, and is also an advanced interaction technology for human-computer interaction systems. In augmented reality systems and virtual reality systems, the purpose of tracking is to obtain the spatial position and direction information of the viewpoint of the user wearing the helmet, and then obtain the key parameters of virtual scene rendering. This is also the key to the correct fusion of virtual and real information in augmented reality systems. [...
